    摘要:

    为定量分析四驱电动汽车液压制动能量再生系统的制动效能和蓄能能力,设置再生制动系统单独制动仿真。液压二次元件以泵的形式运行,建立蓄能器数学建模,对汽车制动时的受力进行运动学分析,然后在AMESim软件上搭建仿真模型。由于蓄能器最低工作压力是影响蓄能器效能的关键参数,进而也是影响液压制动能量再生系统制动效能的关键因素,所以赋予蓄能器不同的最低工作压力进行对比仿真分析。仿真结果表明:当蓄能器最低工作压力为 17 MPa时,在保证四驱电动车液压再生制动系统有较高的制动能效的同时,可以获得较高的蓄能器效能。

    Abstract:

    For the quantitative analysis to braking efficiency and energy storage capacity of four-wheel drive electric vehicle hydraulic braking energy regeneration system,regenerative braking power system was simulated separately.Hydraulic secondary element was operated in the form of pump. The mathematical modeling of the accumulator was built.The kinematics analysis was carried on when the car was braked,then the AMESim simulation model was built.Due to the accumulator minimum working pressure was the key to influence the accumulator performance parameters, compared analysis under the accumulator with different minimum working pressures was done.The simulation results show that when the accumulator minimum working pressure is 17 MPa,it is guaranteed four-wheel drive electric vehicle braking hydraulic regenerative braking system has higher efficiency, at the same time,higher accumulator performance can be obtained.
